wAarnve-nmcnmn Application filed March 24., 1920.

To all whom it may con cern Be it known that T, GEORGE A. CLUFF, a citizen of the United States, residing at Clifton, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in WVarping-Vlachines, of which the-following is a specification.

This invention relates to warping machines, and particularly 'to warping machines wherein several warps are wound at once, as in ribbon or edge warping, the principal object being to effect the winding of the warps on separate receiving beams or the like and to make provision for the stopping of the operation as to any particular warp when a predetermined length thereof has been wound. The invention consists in certain novel combinations of pants hereinafter pointed out in connection with the accompanying drawings and finally embodied in the clauses of the claims, said drawings showing in- Figure 1 aside elevation of the improved machine;

Fig. 2 a plan thereof;

Fig. 3 a sectionon line 3-3, Fig. 1;

Fig. 4 a side elevation of the principal moving parts of the stopping mechanism;

Fig. 5 a'plan of certain parts appearing in Fig. 4

Fig. 6a view of certain parts as seen from the side opposite to that appearing inFig. 4; and

Fig. 7 illustrates a detail shown in Fig. 1 and viewed from the opposite side from which it is seen in that figure. I

The creel carrying the spools from which the warps are taken is shown by dottedlines at a in Fig. 1. p

I) designates a suitable frame for the imwarping machine. and 0' is a suitably driven drive-shaft on which at regular intervals are fixed the driving wheels at, said shaft being suitably journaled inthe frame.

0 is a fixed shaft on which are brackets f and g, the former being fixed and the latter fulcrumed thereon; each bracket 9 may be swung up to the limit affordedby a stopbar h. Each bracket 9 has a shaft i journaled therein in such mannerthat inany position o'fthe bracket in moving around its fulcrum the shaft will stand substantially perpendicular to the bracket: in the illustrated construction this is accomplished by providing a fastratchet wheel j on the shaft Specification of Letters Patent.

and securing to the bracket a fork la'which straddles the shaft and holds the ratchetwheel face to face with the bracket (Fig. 7). The ratchet wheel and hence the shaft is kept from rotation except in one direction by a pawl Z. On each shaft 2' is fixed a wheel m, adapted when the bracket is in thedepressed position to rest in peripheral contact with one of the driving wheels 03, at WlllClltlIIlG the other or free end of said shaft 2' is supported by the bracket f, and on each shaft is adapted to be slipped a spool or beam at which preferably has a spline connection therewith, as indicated at 0. The removal from and'placing ofa spool or beam ona shaft is accomplished when the bracket is elevated in the way explained. The warps, it will be understood, are wound up on the spools or beams n.

There is a bar 39 over which all the warps extend from the creel to their respective spools or beams. For each warp there are also a reed g and a tension bracket 1*, the reed being held in a clip 9' which is clamped to a fixed rod 79 and thebracket being pivoted on said rod p and having a roller r under which the warp extends; for each warp there is also a drum 8 of relatively large diameter over which the'warp extends, thedrum being free to rotate due to the friction between it and the advancing warp (which friction may be made effective for the purpose in hand by facing the periphery of the drum with felt or the like 6) which is made to have considerable contact with the periphery of said drum by the guide roller 7" and a glass bar a arranged'at the relatively opposite side of the drum andcommon to all of the warps.

In view of the foregoing it will beseen that the machine is constructed so that the warping operation as to each warp may be made to begin independently of all )the others, and that as fast as each spool or beam becomes filled the operator can remove the filled spool or beam and substitute an empty one while the warping operation as to the other warps is going on. For each unit of the machinethus involved an inclividual means to stop the winding-up operation is provided, as will now be explained:

There is a strut 0 (Figs. 1, 2 and 3) extending across the frame and having downwardly and upwardly projecting brackets to and m (it may also have brackets y to afford rigid support to the free ends of brackets In each two brackets w and w are fulcrumed between their'ends levers a and 2, respectively, the free ends of which respectively form a handle 2 and a seat 2 and the other ends of which are connected by the link 3 (Figs. 1, 2, 3, 4 and 6) which depends somewhat below the levers, the lever system thus formed (being normally held in the full-line position shown in Fig. 4 by means to be explained but impelled by gravity toward the dotted-line position) serving as a shifter means for shifting the beam-including driven member out of contact with the dr1v1ng member (Z. The means to hold the lever system in the fullline position is a curved hook-shaped detent 1 which may be fulcrumed on w concentric with the lever 2 and is adapted to hook over a pin 5 on the link 3; I prefer to provide a notch ,or step '6 on the link which will engage over a certain shaft 7 to be again referred to and assist the detent 4 to support the lever system when in the full-line position, especially since said lever system has attached thereto a weight 8 which insures a precipitous fall of the lever system when released. When the detent is pushed up to clear pin 5 the step 6 slips off shaft 7, due

to the weight of the parts. 7

Means is provided to cause the releasing movement of the detent, the same being movable back and forth and normally impelled in one direction (as by gravity) and adapted to be fed or advanced in the other direction from the driven warp-engaged means (as drum 8) to bring a part thereof into acsaid shaft 7 around whose hub 11 (Fig. 5) is wound a cord 12 which extends over a pulley 13 and has a weight 14 attached thereto,

so that due to gravity the ratchet wheel .tends to rotate in one direction counterclockwise until the cord has become completely unwound. The ratchet wheel is advanced in the other direction, stepby step, from an eccentric 15 on the adjoining'drum 8 through a strap 16 (Fig. 4) on the eccentric, a lever 17 connectedwith the link 16 of the strap and fulcrumedconcentric with the ratchet wheel and a pawl 18 on the lever,

19 being a suitable holding pawl for the ratchet wheel which is fulcrumed on shaft c. On the ratchet wheel is also a sprocket wheel 20 around which and an idler 21 extends a chain;22 which travels through an.

opening in a lug 23 on the detent and has a ball or enlargement 2 1 thereon adapted to 1mpinge against the lug and trip the detent. F ulcrumed on lever 17 is a lifter 25 which is connected with link 3 by the flexible connection 26 and passes through an eye 25 on pawl 18 and has an eye 25" receiving pawl 19.

The operation is as follows: I11 the Working position the parts of each unit stand as shown in Fig. 1 or in full lines in Fig. 1, wherefore, with shaft 0 rotating, the warp will be winding up on the beam u, and in consequenceof the incidental rotation of the drum 8 the ratchet wheel 10 will by the instrumentalities described be turned against the influence of weight 14 step by step, winding upthe cord 12 on the hub 11 of'the ratchet wheel and advancing the chain 22. Ultimately the ball 24: on the chain will engage and trip the detent 4t, whereupon the lever system will fall by gravity to the dotted line position and in doing so elevate the beam-including driven member clear of the driving member (Z, so that the warping operation stops as to the particular unit affected; the fall of the lever system also, through the connection 26, shifts the lifter 25 so that the pawls 18 and 19 are moved .clear of the ratchet wheel, which then turns, .in the direction, opposite to that in which it has been fed step by step, subject to the influence of weight 14: so as to set back the chain 22 to its original or starting position. Having removed the filled beam from shaft z and substituted an empty one (upon ele- 'vating bracket 9 in the manner already fully explained) the operator has only to push down'on handle a to re-set the lever system or shifter means where it will be supported by the detent and shaft 7, as explained, which operation of course leaves the beam-including driven member again 1i311 peripheral contact with the driving memer d. v

The operator may stop the driving ofany beam at will by turning a cam-device or chock 26' (Fig. 1) so that its toe by resting on seat 2 of lever 2 raiseswheel m clearfof wheel d.
